A meteorite gently lands in a 16-storey office tower overlooking the northern ring road. Since the pandemic, this tower has become an artistic residence, where more than 200 contemporary artists have found refuge. Each one of them takes a piece of stellar matter which they bring to their workshops. Then begins a sensory journey with the material, one and plural at the same time, through the creation of contemporary works that gradually flourish in the tower. The departure of the meteorite, followed by that of the residents of the tower, interrupts this creative bubbling.
